The new series of Who Do You Think You Are? on BBC1 continues this Thursday at 9pm with star of stage and screen, Sheridan Smith. Both of her parents were musically talented and Sheridan inherited a love of singing and show business from them. In this week's programme, she is keen to find out if her family connections to the world of entertainment stretch back even further. The programme concentrates on her great great grandfather, Benjamin Doubleday and his famed banjo playing in the 1880s and 1890s. From fame and popularity he falls upon hard times as the fickle nature of show business deals him a crushing blow. However, despite circumstances conspiring against him, he carries on his banjo playing performances, into the early 1900s. If you'd like to find out more before the programme airs later this week, TheGenealogist has a special featured article on Sheridan Smith.
